SPECIFICATION forming part of Letters Patent No. 649,309, dated May 8, 1900.

Application filed July 1,1899. Serial No. 722,557. (No model.)

To all whom 2 25 Hwy concern.-

Be it known that I, SAMUEL J. HUNGERFORD, of Farnham, in the Province of Quebec and Dominion of Canada, have invented a new and Improved Combination-Machine, of which the following is a full, clear, and exact description.

This invention relates to a motor or engine, a lathe, and a drill, all supported on one frame, the object being to economize space IO and make the combined machine easily portable as a whole.

I will describe a combination-machine embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a combination- 20 machine embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1, and Fig. 3 is a section on the line 3 3 of Fig. 1.

Referring to the drawings, 1 designates the bed-plate of a lathe, supported on the frame 2 5 2. The headstock 3 of the lathe has its spindle-bearings in a block 4:, supported on the bed. Secured to one end of the frame is an engine 5, which may be operated by any suitable power. The piston-stem 6 of the en- 30 gine has a link connection 7 with awrist-pin 8 011 a fly-wheel 9, having its shaft-bearings in the frame of the machine. Also connected with the wrist-pin 8 is a link 10 for operating a slide-valve in the steam-chamber 11.

On the inner end of the shaft 12 for the flywheel 9 is a pulley 13, from which a band may extend to drive a grindstone, an emerywheel, an air-blast fan, or the like. A pinion 14: on the shaft 12 meshes with a drive-gear 40 15 on a counter-shaft 16, on which is a steppulley 17, from which a band 18 extends to a step-pulley 19 on the spindle of the headstock.

Rigidly mounted on the end of the counter- 5 shaft 16 is a friction cone or block 20, de-

signed to be engaged by the step-pulley 17 to cause said step-pulley to rotate with the shaft. The step-pulley is moved into and out of engagement with the block 20 by means 50 of a shifting rod 21, connected at one end to abar 22, which is pivoted at its lower end to the frame of the machine, and at its opposite end said shifting rod is connected to the bar 23, the lower end of which is attached to a rock-shaft 2%. Attached to this rock-shaft 24 is a link 25, which has a link connection 26 with a yoke 27, havinglugs 28, which engage in an annular channel formed in the step-pulley 17.

Mounted on a bracket 29, secured to the frame of the machine, is a drill-stock 30, be low which is the vertically-adjustable table 31. The drill stock is rotated from the spindle of the head-stock by means of apinion 32, meshing with a pinion 33 on a shaft 34, which has on its outer end a bevel-gear 35, meshing with a bevel-gear 36 on the drill stock. The pinion 32 is designed to be moved out of engagement with the pinion 33 when it is not desired to operate the drill. I have there fore shown said pinion 32 as mounted to slide on the spindle to disengage it from the gearwheel 33. The pinion 32 is moved by means of a shifting rod 37, having ayoke 38, provided with lugs 39, engaging an annular channel formed in a projection 40 on the pinion 32.

The usual screw-cutting or feed-gears 41 42 are mounted in the frame and operated in the usual manner. Connected with the gear 12 is the usual screw-shaft 43 for moving the tool-carrier 44 upon which the usual tool-post is mounted.

Several advantages may be claimed for this machine-that is, it is much more cheaply built than the three machines could be built separately, it is more easily transported, and requires no setting up, as it is ready for instant service in any place where steam or other source of power is available. It occupies less floor-space than three separate or independe'nt machines,and there is an economy in shafting and belting. The machine is especially designed for use in railway-roundhouses, factories, mills, with contractors plants, or on shipboard, and, in fact, in any place where a limited amount of machine-work of a wide variety is required, such as repairing breakdowns, &c.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a frame, of a lathe on the frame,a motor on the frame and having driving connection with the lathe, a bracket secured to the frame, a drill-stock mounted in the bracket, a pinion on the lathe-spindle, ayoke engaging'with the said pinion, a shiftingrod extended from the yoke,a shaft mounted to rotate in the bracket, a pinion on said shaft for engaging with the pinion on the lathe-spindle, and gear connection between the shaft and the drill-stock, substantially as specified; Y

2. The combination with a machine-frame of a motor thereon, a lathe having the headstock spindle driven from the motor, and a drill-stock supported by a bracket from the head-stock and geared to the head stock sp'in"- dle, the bracket having a member bridging the head-stock and secured to the inner end of the same, and a member secured to the outer end of the head-stock.

3. The combination with a single frame, of an engine mounted on said frame, a countershaft driven by the engine, a pulley loosely mounted on the counter-shaft, a clutch for rotatively engaging the pulley With the shaft, a lathe on the frame, a pulley on the spindle of said lathe and having a band connection with the first-named pulley, and a drill-stock on the frame and adapted to be driven from the lathe-spindle, substantially as specified.

4:. The combination with asingle frame, of a counter-shaft mounted in the frame, an engine mounted on the frame, a driving-shaft operated by the engine, a gear connection be tween the driving-shaft and counter-shaft, a band-pulley on the driving-shaft, a lathe on the frame and operated from the countershaft, and a drill-stock on the frame adapted to be operated from the lathe-spindle, substantially as specified.
